Bio:William Amos, son of man who mated with a female Deviant. His mother was killed by Tantalus. Mammoth joined the Underground Legion, and became its leader after Blackwulf was killed. He was constantly warned by the Peacekeeper Wraath to avoid becoming like him- as Wraath is apparently Mammoth's future self- but he was unsuccessful, and Mammoth would have been killed by the Black Legacy of Tantalus, had Blackwulf II not sliced off his left him.
